    • Immunofluorescence staining of MCF7 cells with purified ab32524 working dilution of 1/500, counter-stained with DAPI. The secondary antibody was an Alexa Fluor® 488 conjugated goat anti-rabbit (ab150077), used at a dilution of 1/1000. The cells were fixed in 100% methanol. The negative control is shown in bottom right hand panel - for the negative control, PBS was used instead of the primary antibody.

    • Anti-ARF1 + ARF3 antibody [EP442Y] (ab32524) at 1/2000 dilution + HEK-293 cell lysate

      Predicted band size: 21 kDa
      Observed band size: 20 kDa (why is the actual band size different from the predicted?)

    • Immunohistochemical analysis of paraffin-embedded human breast carcinoma using ab32524 at 1/250 dilution.
    • Overlay histogram showing HeLa cells stained with ab32524 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab32524, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

    Thank you for your enquiry.

    I contacted the laboratories regarding the unsuitability of this antibody for ICC-IF. When it was tested, it showed incorrect staining localization. It worked well in the other applications listed on the datasheet....
